Chōkaisan Ōmonoimi Shrine

Chōkaisan Ōmonoimi Shrine, also known as Chokaisan Ōmonoimi-jinja, is a Shinto shrine on Mount Chokai in Yamagata Prefecture, Japan. The shrine has three parts on different parts of the mountain: Fukura-kuchinomiya and Warabioka-kuchinomiya at the foot of the mountain and easier to access for visitors, and the main shrine – known as Sanchō-Gohonsha – on the mountain's summit. The Shrine is a national historic site.

The shrine is primarily dedicated to Omonoimi no Kami, the unique kami of the shrine, but also worships Toyoukebime and Tsukuyomi-no-Mikoto. Omonoimi no Kami is considered possibly identical to Toyouke-hime who is also worshipped at the Warabioka subshrine. Omonoimi no Kami is primarily associated with industrial growth and is also enshrined in other places in the Tōhoku region, including Chōkai gassan ryōsho-gu.
